That looks pretty good Juan, but honestly I'm not super impressed with the spool of this turbo. We just did a street pull in the car you were comparing this to and here is the boost plot:
That's 20psi by 4000RPM and 25psi before 4300RPM and this is a GT35R with .82 housing with a FMIC. Of course this is a rotated setup, so its not a direct comparison. Oh and this is 4th gear in an 05 STI. The car did 475whp on our dyno (558whp Dynojet).
